UNITED STATES PATENT OritceQ JOSEPH JACOB ILLINGWORTH, OF BROOKLYN,lNEW' YORK.

IMPROVEMENT FOR CLEANING TUBES IN BOILERS.

Specification forming part of Letters Patent No. 48,94 S, dated July 25,1865.

To all whom it may concern:

Beit-,known thatI, J osEPH J ILLINGWORTH, ot' Brooklyn, in the county ofKings and State of NewYork, have invented a new and useful Improvementin Cleaning Tubes and Flues of Steam-Boilers; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to fully understand and usethe same, reference being had to the accompanying d rawing, forming partof this specification.

The drawing, consisting only of one ligure, represents an elevation of avertical longitudinal section of a steam-boiler with my apparatusapplied to one of its tubes. f

This invention consists in a device, hereinafter described, for cleaningthetlues and tubes of steam-boilers by means of a jet or current ofsteam directed through said tubes and ues.

Arepresentsalongitudinal section ofatubular boiler, B its steam-dome, Hthe furnace, G the furnace-door, and I the place of its backconnections. a a a ay represent some of the tubes of the boiler.

The tubes of steam-boilers are apt to become foul with soot, ashes, andcinders from the furn nace, the blast which enlivens the fire sometimescarrying cinders and smallffragments of coal out ot' the fire into thetubes. The collection of ashes and cinders continues to accumulate untilsome of the tubes are nearly or quite closed,and all of them more orless obstructed and the draft of the furnace in a manner destroyed. Whenany ofthe tubes leak the water from the boiler mingles with the ashesand soot or other matter deposited in them, and they acquire a moredense and solid character, which is increased by the heat of theproducts 4 of combustion, so that the deposits are recleaning the tubesof steam-boilers I employ a flexible hose or tube, D, connected by asteamcock,O, with the steam-dome B or other suitable part of the boiler,so as to cause dry steam to pass through the hose.

Eis a pipe to which the free end of the hose is attached, and which hasa nozzle, b, of such a diameter as to tit easily in the tubes a of theboiler. This nozzle may have perforated sides, or its sides may havelongitudinal openings therein, as shown in the drawing.

F is a rod, secured to the pipe E by means ofa collar or other usualdevice. Its length is to be such as to extend out beyond the door ofthefurnace when the pipe is applied to any of the tubes, and its purpose isto enable the fireman to control and direct the hose, and so be able toinsert the pipe in any tube and Withdraw it at pleasure, and to hold itat any dei sired position within the furnace, so as to cleanse its wallsby the action of the steam. The hose is to be ofsuch a length as toenable one to insert its free end in any of the tubos.

The manner of lusing the apparatus'for cleaning the tubes of a boilerand for cleansing the sides of the lire-chamber is as follows: The firebeing withdrawn from the furnace, the nozzle I) is placed in the mouthof one of thetubes by means of the handle or rod F, and steam is allowedto pass through the hose into the tube. The force of the steam in itspassage through the tube clears out the ashes and cinders and othermatter deposited therein and drives them into the space I of the backconnection ot' the boiler. This treatment is applied to each tube insuccession until all are thoroughly cleaned. The deposits are afterwardremoved from the space I in the usual manner. The walls of thetirechamber are likewise cleaned of the ashes and soot deposited on themby turning the current of steam against them in every direction by meansof the rod F.

It is not necessary to withdraw the fire or let it die out in order touse the hose in the tubes orin the tire-chamber; but if itis desired toclean the tubes or the walls of the fire-chamber while the fire is keptup, it can be done with good effect and without injury to the hose fromthe heat ofthe fire by applying the hose immediately after fresh fuelhas been applied I claim as new and desire to secure by Let ters Patent-The nozzle E b and flexible pipe D, applied substantially as hereindescribed, for cleaning iiues or tubes of steam-boilers.
